Combining the above advice and illustration, with several more recent
comments about indentation revealing structure, should the above be
amended to:
indent = " " # your choice of how many spaces/tabs
...
print( "i is", i )
...
print( indent + "j is", j )
...
print( indent + indent, var ) # add sep="" if pernickety
...
Thus, the output matches the code and each complements the other's view
of structure!
